Complete, uncut output of your MPlayer call (fps and ni have no effect in your command line, ao sdl is not recommended)
If your sample is really 1920p60, it will not play with current VDPAU hardware (without -lavdopts skipframe=nonref), if it is a PAFF sample, you need -nocorrect-pts (and possibly -delay -0.3 or similar).
The HF20 records at 60i not 60p.
The term "CPU gets crushed" means he sees high CPU usage.
